Abstract

The green chemistry promotes the synthesis of nanomaterials from plant extracts as a new climate intelligent alternative to the use of conventional protocols based on costly and toxic chemicals. Therefore, this research was undertaken to analyses the efficiency of banana (peels and rachis) waste extracts in the production of a micro-composite composed by silver nanoparticles (AgNPs) and cellulose microfibers (CMF) respectively. Results showed the synthesis of 24 nm diameter spherical particles AgNPs, with a peak of absorbance at 410 nm, in (v/v) water:ethanol extracts of banana peels at a final dilution of 3.10-2. Concomitantly, 50-350 µm in length and 5-10 µm of diameter CMF were obtained via the oxalic acid hydrolysis of the oven-dried banana rachis. The micro-composite (AgNPs-CMF) and AgNPs displayed an active reducing capacity over 60% determined by the DPPH test, and active bacterial activity against E. Coli and S. aureus in Petri dishes. Overall results support the use of banana waste for the synthesis of AgNPs and CMF for industrial purposes.

香蕉(Musa acuminata)废料纳米银和纤维素微纤维复合材料:绿色合成、抗氧化性能和抗菌能力

绿色化学促进了从植物提取物中合成纳米材料，作为一种新的气候智能替代品，取代了基于昂贵和有毒化学品的传统协议。因此，本研究分析了香蕉（果皮和果轴）废料提取物在生产分别由银纳米颗粒（AgNPs）和纤维素微纤维（CMF）组成的微复合材料中的效率。结果显示，在最终稀释度为3.10-2的香蕉皮的（v/v）水：乙醇提取物中合成了直径为24nm的球形颗粒AgNPs，在410nm处具有吸收峰。同时，通过对烘干的香蕉轴进行草酸水解，获得了50-350µm长和5-10µm直径的CMF。通过DPPH测试，微复合物（AgNPs CMF）和AgNPs显示出超过60%的活性还原能力，并且在培养皿中对大肠杆菌和金黄色葡萄球菌具有活性细菌活性。总体结果支持将香蕉废料用于工业目的合成AgNPs和CMF。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
